Abstract

Novel monomers of the general formula ##STR1## where b is 0 or 1, a is 1, 2, 3 or 4, R2 is a monovalent alkyl radical and R is an organic radical. The novel monomers may be employed to produce novel copolymers useful as hydrogel, soft non-hydrogel and/or rigid gas permeable contact lens materials.

Description

BACKGROUND OF THE INVENTION
Biomedical materials which are particularly useful as contact lens materials fall into three general classifications; hydrogels, non-hydrophilic soft materials and rigid gas permeable materials.
The chemistries of contact lens hydrogels are almost completely described by polymer and copolymer systems comprised of either 2-hydroxyethylmethacrylate (HEMA) or N-vinyl-2-pyrrolidinone (NVP), or mixtures of HEMA and NVP. Minor components such as crosslinking agents are used in these systems to control tear strength, hydrolytic stability, modulus, etc. These hydrogel systems are generally well known and have been successful on a commercial basis, but they are not without shortcomings.
Polysiloxane based elastomers have also been known in the contact lens art for some time and have enjoyed limited commercial success. In general, the silicone chemistries involve vinyl functional end capped polysiloxane polymers.
Rigid gas permeable contact lens materials are generally copolymers formed from copolymerizing acrylic or methacryl functional monomers which contain siloxane functionalities and often also contain fluorine atoms.
The present invention provides a novel monomer chemistry to the art of biomedical device materials.
SUMMARY OF THE INVENTION
The present invention provides novel monomers useful in biomedical devices. These novel monomers have the general formula ##STR2## where b is 0 or 1, a is 1, 2, 3 or 4, R2 is a monovalent alkyl radical and R is an organic radical. The novel monomers may be employed to produce novel copolymers useful as hydrogel, soft non-hydrogel and/or rigid gas permeable contact lens materials.
DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to new crosslinked copolymers which employ novel monomers also disclosed in this application. These novel copolymers are particularly useful as biomedical materials, and are especially useful in the area of contact lens applications. These new crosslinked copolymers, when used in contact lens applications, can produce a wide variety of types of contact lens materials ranging from hard, gas permeable lens materials; soft, hydrogel lens materials; to soft, non-hydrogel lens materials.
The novel monomers generally fall into the following classifications: a) hydrophilic monomers with the general formula ##STR3## where b is 0 or 1; a is 1, 2, 3 or 4
X denotes --NH--, --S-- or --O--; and
RH denotes a hydrophilic moiety such as an organic radical with one or more amide hydroxyl, urea or carboxylic acid functionalities so that the monomer as a whole is relatively hydrophilic;
b) silicone containing monomers of the general formula ##STR4## where a, b, and X are defined as above and RSi denotes a silicone containing organic radical;
c) non- or slightly hydrophilic monomers of the general formula ##STR5## where a, b and X are as defined above and RNH denote a non-hydrophilic organic radical.
In general, there are no clear cut demarcations between any of the three classifications of contact lens materials. However, in general, hydrogel materials should have oxygen permeabilities with DK's greater than 20×10-11 cm3 ×cm/sec.×cm2 ×mmHg (or DK units hereinafter) and preferably greater than 40 DK and most preferably greater than 60 DK. They should have a Young's modulus of elasticity in the range of 20 to 400 g/mm2, preferably 50 to 200 g/mm2 as measured by ASTM test method D 638. They should have tear strengths greater than 1 g/mm2 and preferably greater than 5 g/mm2 as measured by ASTM test method D 1938. Their water content should be between 10 to 80%, and preferably between 20 to 50%. The contact angle, which is a measurement of the wettability of the lens, should be less than 80° and should preferably be less than 40°. The protein uptake of hydrogel lenses or hydrogel lens materials should be less than or equivalent to that of PHEMA.
Soft, non-hydrogel materials should have at a minimum oxygen permeabilities equal to or greater than hydrogel materials. The water content should always be less than 10%, and preferably less than 5%. The modulus of elasticity should be between 20 and 5,000 g/mm2 and preferably should be in the range of 50 to 250 g/mm2. Contact angle less than 80° and preferably less than 40° and the tear strength (both initial and propagation) of this material should be in excess of 5 g/mm2.
Properties of hard, gas permeable lens materials should be similar to that of the hydrogel and the soft, non-hydrogel materials. In addition, the glass transition temperature of such materials should be greater than 40° C. and preferably greater than 65° C. The modulus of the material should be greater than 50,000 g/mm2 and preferably greater than 75,000 g/mm2.
HYDROGEL MATERIALS
To prepare a soft, non-hydrogel material the following prepolymer formulations should be used: (a) between 25 and 90% of the prepolymer mixture should comprise a hydrophilic monomer portion. This portion will preferably comprise in part at least a hydrophilic monomer represented by the general formula ##STR6## where b is 0 or 1 and X is --S--, --O--, or --NR3 -- and Rh denotes a relatively hydrophilic moiety. This hydrophilic monomer portion may also include at least one of the hydrophilic monomers chosen from the group consisting of wetting monomers N-vinyl-2-pyrrolidinone, 2-hydroxyethyl vinyl carbonate, 2-hydroxyethyl vinyl carbamate, 3-(2-pyrrolidinon-1-yl)-propyl vinyl carbonate, 2-(2-pyrrolidinon-1-yl)ethyl vinyl carbonate, N-(vinyloxycarbonyloxy)pyrrolidin-2,5-dione, N-[vinyloxycarbonyloxyethyl]pyrrolidin-2,5-dione, N-vinylacetamide, N-methyl-N-vinylacetamide, N,N-dimethyl vinyl carbamate, N,N-diethyl vinyl carbamate. These monomers may, of course, comprise only a portion of the hydrophilic monomer portion of prepolymer mix which can further be comprised of other hydrophilic monomers.
The hydrogel prepolymer formulation should also preferably contain (b) between 40 to 80 weight percent of a non- or weakly hydrophilic monomer as combination of monomers chosen from the group consisting of 3-[tris(tri-methylsiloxy)silyl]propyl vinyl carbonate, t-butyl vinyl carbonate, t-butyldimethylsiloxyethyl vinyl carbonate, 3-[tris(trimethylsiloxy)silyl]propyl vinyl carbamate, 3-(vinyloxycarbonylthio)propyl[tris(trimethylsiloxy)]silane, 3-[tris(trimethylsiloxy)silyl]propyl allyl carbamate, t-butylphenyl vinyl carbamate. These non- or slightly hydrophilic monomers enhance the oxygen permeability of the final copolymer.
The hydrogel prepolymer compositions further comprise (c) between about 0.1 to 10% of a crosslinking agent, which may be chosen from a list of preferred crosslinking agents later disclosed in this application, or one of the crosslinking monomers known in the prior art as exemplified and/or taught in U.S. Pat. Nos. 4,060,678; 4,182,822; 4,267,295; 4,640,941 and/or 4,690,993.
The amount of hydrophilic monomer used to prepare the hydrogel material in the present invention is adjusted within the above limits to give a water content in the hydrated hydrogel of from about 5 to approximately 80% by weight. The non- or weakly hydrophilic monomer content is adjusted within the stated limits to maximize other desirable properties such as oxygen permeability, modulus and/or tear strength. The quantity of the crosslinking monomer used to produce a hydrogel material is adjusted to maximize desirable properties such as water content, modulus, lens strength, and also aids in the hydrolytically stability of the final material. In addition, UV absorbing monomers or tinting monomers may also be added to enhance the properties of the final material.
For instance, the following prepolymer formulations would produce hydrogel materials within the scope of the present invention.

HARD, GAS PERMEABLE MATERIALS
Hard lenses are prepared using: (I) one or more of the non-hydrophilic monomers of the present invention; (II) a crosslinking agent; (III) a small amount of a wetting monomer; and (IV) optionally other agents such as strengthening agents or UV absorbing or dye monomers. The three main components are used in the following ratios; the non-hydrophilic monomer component (I) is used in amounts of about 60 to about 95 weight percent, the crosslinking monomer (II) in amounts from 0.1 to 10 weight percent, and the wetting monomer (III) in amounts from about 1 to 20 weight percent. The content of the crosslinking agent is chosen to provide a dimensionally stable lens material resistant to breakage and stress crazing. The amount of wetting monomer used is adjusted within limits to provide sufficient wetting characteristics so as to maintain a stable tear film while at the same time keeping a sufficiently low water content.
The non-hydrophilic monomers used to make the hard contact lens materials include one or more of the following monomers: 2,2,2-trifluoroethyl vinyl carbonate, 2,2,2-trifluoroethyl vinyl carbamate, 1,1,1,3,3,3-Hexafluoroprop-2-yl vinyl carbonate, 2,2,2-trifluoroethyl allyl carbonate, 2,2,2-trifluoro-1-phenylethyl vinyl carbonate, trimethylsilylmethyl vinyl carbonate, trimethylsilylethyl vinyl carbonate, 3-(trimethylsilyl)propyl vinyl carbonate, t-butyldimethylsiloxyethyl vinyl carbonate, 3-[tris(trimethylsiloxy)silyl]propyl vinyl carbonate, 3-[tris-(trimethylsiloxy)silyl]propyl vinyl carbamate, 3-(vinyloxycarboxylthio) propyl-[tris(trimethylsiloxy)silane].
The crosslinking agents used preferably to make hard contact lens materials include crosslinking agents known in the prior art as taught in the U.S. patents referenced supra, but most preferably crosslinking agents chosen from the group consisting of crosslinking monomers represented by the formula ##STR7## wherein: X denotes --S--, --O--, or --NH-- and at least one X denotes a --NH-- in formula B; b is 0 or 1;
Rc1 denotes a multivalent organic radical and a is 2, 3, or 4; and Rx1 denotes a divalent organic radical.
The preferred crosslinkers includes:
1,5-bis-(vinyloxycarboxyloxy)-2,2,3,3,4,4-hexafluoropentane;
1,2-bis(vinyloxycarboxyloxy)ethane;
α,ω-bis(vinyloxycarbonyl)polyethylene glycol;
N,O-bis(vinyloxycarbonyl)ethanolamine;

1,3-bis-[4-(vinyloxycarbonyloxy)but-1-yl] tetramethyldisiloxane;

The wetting monomers useful in hard contact lenses include N-vinylpyrrolidinone, 2-hydroxyethylmethacrylate, itaconic acid, methacrylic acid, N,N-diethylacrylamide, N,N-diethyl vinyl carbamate, N,N-dimethyl vinyl carbamate, N-Methyl-N-Vinyl acetamide, and all hydrophilic monomers listed in the hydrogel section supra.
SOFT, NON-HYDROGEL MATERIALS
Soft, non-hydrogel contact lens materials with little or no water content can be prepared by polymerizing prepolymer mixtures with the following formulations: between 50 and 90 weight percent of non-hydrophilic monomers with the following general formula: ##STR9## where X denotes either --O--, --S-- or --NH--; and
RNH represents an organic radical that is largely non-hydrophilic, and a is 1, 2, 3 or 4;
from 5 to about 25 weight percent of a hydrophilic monomer and between 0.1 and about 10% of a crosslinking monomer.
RH, the largely non-hydrophilic moiety in the above formula, is typically a monovalent radical--but it may be multivalent. The main functional requirement is that it is largely non-hydrophilic, generally nonreactive to free-radical vinyl addition reactions and may be incorporated into the above formula from a synthetic perspective.
In general, RNH may be described by the following formulae: ##STR10## where R1 denotes a monovalent organic radical such as an alkyl radical with 1 to 6 carbon atoms, or a fluoroalkyl radical with 1 to 6 carbon atoms;
Rc1 denotes ##STR11##

The copolymers of the present invention are formed by way of a free radical polymerization the details of which are generally known in the art. In general, the various comonomers are chosen and combined, as required to form the desired final copolymers, and a free radical catalyst is added to the mixture. The mixture is then polymerized to form the desired copolymer.
Free radical catalysts are known in the art and are mostly of two general types: heat initiated free radical catalysts, and photoinitiated free radical catalysts, more specifically, ultraviolet radiation initiated free radical catalysts. Heat initiated catalysts include peroxides such as 2,5-dimethyl-2,5-bis(2-ethylhexanoylperoxy) hexane (Lupersol 256™ Pennwalt Chemicals), bisisopropylperoxydicarbarate, acetylperoxide, lauroyl peroxide or benzoyl peroxide, photoinitiators include compounds such as 2-hydroxy-2-methyl-1-phenylpropan-1-one (Darocur™, EM Chemicals), and the like.
Diluents may be employed in the process of polymerizing the copolymers of the present invention in order to modify the resultant physical characteristics of the finished copolymer. For instance, the comonomer mixture used to produce a hydrogel like material may also include a portion of methylethylketone. In general, the amount of diluent used should be less than 50 wt. %. In most cases, the diluent content will be less than 30 wt. %. In a particular copolymer system, the actual limit will be dictated by the solubility of the various comonomers in the diluent. In order to produce an optically clear copolymer, it is important that a phase separation does not occur between the comonomers and the diluent, or the diluent and the final copolymer.
Furthermore, as a practical matter, the maximum amount of diluent which may be used will depend on the amount of swelling the diluent causes the final copolymers. Excessive swelling will or may cause the copolymer to collapse when the diluent is replaced with water upon hydration.
Suitable diluents include ethyleneglycol; glycerine; liquid polyethyleneglycol; alcohols; alcohol/water mixtures; ethylene oxide/propylene oxide block copolymers; low molecular weight linear polyhydroxyethylmethacrylates; glycol esters of lactic acid; formamides; ketones; dialkylsulfoxides; butyl carbitol; and the like.
These novel copolymers in general are made from polymerizing mixtures comprising:
a) from 1 to 99 wt. % of a base monomer of the general chemical formula ##STR12## wherein:
X denotes an --O--, --S--, or --NR3 -- divalent radical;
R1 denotes an organic radical;
R2 denotes --H or --CH3 ;
R3 denotes --H, or a monovalent alkyl radical;
a is 1, 2, 3, or 4; and
b is 0 or 1.
b) from 0.1 to 20 wt. % of a crosslinking agent known in the biomedical material art, or a novel crosslinker represented by the chemical formulae: ##STR13## wherein: X is --O-- or --NH-- with at least one X being --NH--; Rc1 denotes a multivalent organic radical, b is 0 or 1, and a is 2, 3 or 4.
These copolymers may also contain further additives such as wetting agents, tints, dyes, strengthening agents and the like to tailor specific material properties as desired.
The copolymers of the present invention are useful as biomedical devices, and in particular, are well suited as contact lens materials. The copolymers can be formed into contact lenses by many of the techniques known in the art to be useful in contact lens production. For instance, prepolymer mixtures containing heat initiated free radical catalysts can be placed in polypropylene tubes which are then heat cured over time to form copolymeric rods which are then cut to form button shaped articles. These button shaped articles can then be lathed into contact lenses.
Alternately, the prepolymer mixture can be molded per the methods disclosed in U.S. Pat. Nos. 4,085,459 or 4,197,266. Spin casting techniques may also be used with the present materials and such methods as described in U.S. Pat. Nos. 3,408,429 and 3,496,254 can be so adopted to be useful with the present copolymers.

These films were prepared by placing the prepolymer mixtures between glass plates separated by a Teflon® peripheral gasket and were UV irradiated for 2 hours. The samples were then prepared for physical characterization.
Physical properties for films were determined using the following test procedures:
1. Tensile strength (g/mm2) and modulus of elasticity were measured per ASTM test a method D1708.
2. Elongation was measured per ASTM 1708.
3. Initial tear strength and propagation tear strength were measured per ASTM 1438.
4. Oxygen permeabilities were measured by the method reported by Relojo, M. et al in Contact and Intraocular Lens Medical Journal, Vol. 3, issued p. 27 (1977) and edge effects were accounted for per the methods described by Fatt, et al. in International Contact Lens Clinic, v. 14, p. 389 (1987).
5. Water content is measured per a gravimetric method.
6. Refractive index was measured per typical methods on hydrated samples using a refractometer.
